SPECIFICATION forming part of Letters:Patent No. 625,1 50, dated May 16, 1899.

Application filed October 8, 1898. Serial No. 692,971. (No model.) i

The pairs of enlargements card-cylinder-operating levers, the former bep p and t t are connected by an intermediate ing fulcrumed at cl in the standard 6 of the member, which consists of a pair of spaced jacquard-machine and the latter being fuldisks-u u, integrally formed with a connect- I ing and compound web u in such manner that said disks are relatively situated in planes which intersect each other at right angles. The disks are pivotal] y arranged between the enlargements upon boltsoo, which penetrate said disks and intermediate circular bearings w w, situated in central openings in said disks.

In order to produce as much freedom of movement as possible, the circular bearings w w are made slightly thicker than the disks. Furthermore, when the bearings are properly bolted together, so that the circular bearings are tightly secured between the disks, no movement will be permitted between said bearings and the bolt, and consequently the strain and wear which would otherwise be borne by the bolt alone is practically taken up by the circular bearings and the disks. The bolt may also share in bearing the strain; but if the parts are clamped together tight enough to prevent any turning of the bearing on the bolt there will be no wear upon the latter.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a knuckle-joint, the combination of two substantially similar members,said members being disposed in intersecting planes andeach comprising a pair of spaced sections, a third connecting member having its extremities pivotally arranged between the sections of each pair, and a bearing situated between said sections and upon which each extremity of said connecting member is pivoted, said bearing being of greater thickness than that of said extremity, substantially as described.

2. In a knuckle-joint, the combination of two substantially similar members, said members being disposed inintersectin g planes and each comprising a pair of spaced and integrally-connected circular sections,a third connecting member comprising integrally-connected disks pivotally arranged between the sections of each pair, a circular bearing upon which each disk is pivoted, said bearing being of greater thickness than said disk, and a bolt penetrating said sections of each member and its circular bearing,substantially as described.

3. A flexible connection between a lever of a jacquard-machine and a crank for operating said lever, consisting of a connecting-rod adj ustably and operatively connected to said crank and a knuckle-joint consisting of two members, one of said members being adapted to be adjustably connected to said lever and the other of said members being adjustably secured to said connecting-rod,and each comprising a pair of spaced and integrally-connected circular sections, a third connecting member comprising integrally connected disks pivotally arranged between the sections of each pair, acircular bearing situated between said bearings and upon which each disk is-pivoted, said bearing being of greater thickness than that of said disk,-and a bolt penetrating said sections of each member and its circular bearing, substantially as described.

4. The combination with an operating-leverfor a jacquard-machine and with a crank for operating said lever, of a pitman pivotally connected to said crank,a connecting-rod adjustably connected to said pitman and a knuckle-joint consisting of two members, one of 'said members being adjustably connected to said lever and the other of said members being ad justably secured to said connectingrod, and each of said members comprising a pair of spaced and integrally-connected circular sections, a third connecting member comprising integrally-connected disks pivotally arranged between the sections of each pair, a circular bearing upon which each disk is pivoted, said bearing being of greaterthickness than said disk, and a bolt penetrating said sections of each member and its circular bearing, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 26th day of September, 1898.

WILLIAM ORUTCHLOWV.
